Add components
In ADCM, a component means a part of a service that should be deployed on one or several cluster hosts.

IMPORTANT
Initially, there are no components on any of cluster hosts. You should map components to hosts manually.

The steps for adding components to hosts are listed below:
-
Select a cluster on the Clusters page. To do this, click a cluster name in the Name column.
Select a cluster -
Open the Mapping tab on the cluster page.
